Sensor handling
Never attempt to disassemble the electrochemical type sensor inside the product. Electrolyte
contained inside may cause inflammation if it comes into contact with the skin. There is also a risk
of blindness if it comes into contact with the eyes. Electrolyte may discolor or decompose clothing
if it comes into contact with clothing. If contact occurs, rinse the area immediately with plenty of
water. Do not use any gas other than nitrogen as the balance gas when calibrating or adjusting an
oxygen sensor.
Fresh air adjustment in the atmosphere
When fresh air adjustment is performed in the atmosphere, check the atmosphere for freshness
before starting. The presence of interference gases will make it impossible to adjust the product
correctly, resulting in the danger of erroneous detection when actual gas leaks occur.
Action when a gas alarm occurs
When a gas alarm occurs, this indicates an extremely dangerous situation. The user must take
appropriate action after taking steps to ensure safety.
Battery level check
Check the battery level before using the product. The battery may be depleted when the product is
used for the first time or after extended periods without use. Charge the battery before use.
If a low battery voltage alarm occurs, gas cannot be detected. If the alarm is issued during use,
turn off the power and promptly charge the battery in a safe place.
Miscellaneous
Gas cannot be detected if the sensor is covered with water such as rainwater. Do not use the
product in rain or submerge it in water.
When wearing the product, make sure that it is exposed to the air. If it is covered or blocked,
correct measurement cannot be obtained, possibly resulting in accidents.
Do not dispose of the product into fire.
Do not attempt to wash the product, either in a washing machine or an ultrasonic cleaning
machine.
Do not block the buzzer sound opening. Doing so will muffle or silence the audible warning.
